Painting with the Art History & History Brushes
What does the Art History Brush do?
You can create some interesting painterly effects with the art history brush.
The art history brush tool uses the source data from a specified history state or snapshot of the image. You can experiment with different paint styles, sizes, and tolerance options, to simulate the texture of painting with different colors and artistic styles.
The art history brush is different from the history brush, which recreates the specified source data. The art history brush uses the source data in the image snapshot along with your options to create different colors and artistic styles.
What does the History Brush do?
The history brush will remove changes selectively that you make to an image.
